' Patented Nov. 5, 1907.

Application filed March 9,1907. Serial No. 361,511.

To all whom it may concern;

Be it known that 1, CHARLES F. SMITH, a citizen of the United States, residing at Miami, in the county of Dade and State of Florida, have invented a new and useful Lock for the Glosures'of Window-Frame Pockets, of which the following is a specification.

This invention relates to closures for window frame pockets and has for its object to provide a comparatively simple and inexpensive device of this character which may be readily removed to expose the sash weights without danger of scratching or otherwise marring the wood-work.

A further object is to provide means for locking the closure or pocket piece in operative position and means for yieldably supporting the same in its seat in the window-frame or stile.

A further object is to form the pocket piece with an opening. or recess through which a suitable tool may be introduced for releasing the locking mechanism when the parting strip is to be removed from the window frame.

A still further object of the invention is to generally improve this class of devices so as to increase their utility, durability and efiiciency.

Further objects and advantages will appear in the following description, it being understood that various changes in form, proportions and minor details of construction may be resorted to within the scope of the appended claims' In the accompanying drawings forming a part of this specification: Figure 1 is a front elevation partly in section of'a portion of a window frame provided with a pocket closure constructed in accordance with my invention. Fig. 2 is a longitudinal sectional view of the same. Fig. 3 is a vertical sectional view taken on the line 33 of Fig. 2. Fig. 4 is a perspective view of the upper portion of the pocket piece.

Similar numerals of reference indicate .corresponding parts in all of the figures of the drawings.

The improved closure or pocket piece is principally designed for use in connection with window sashes and similar sliding closures in which counter-weights are employed for balancing the sashes and by way of illustration is shown in connection with a window of the ordinary construction in which 5 designates the windowframe, the vertical stile 6 of which is provided with an opening which communicates with the weight-receiving pocket 7 and through which access may be obtained to the weights 8 when the suspension cord 9 becomes severed or otherwise detached from the weights.

The opposite end walls of the weight receiving opening are inclined or beveled, as indicated at 10 for engage ment with the correspondingly inclined or beveled ends of the removable pocket piece or closure 11, the latter being provided with a longitudinally disposed groove or rabbeted edge 12 which registers with the groove 13 in the vertical stile 6 when said closure is in operative position and forms a continuation of the groove 13 thereby to accommodate the pocket strip or stop 14.

Secured to the inner wall of the weight-receiving pocket 7 in any suitable manner as by screws or similar fastening devices 15 is a spring plate 16 the free end of which is curved laterally and bears against the adjacent inner face of the pocket piece 11 and serves to yieldably support the latter in engagement with the adjacent correspondingly inclined wall of the closure receiving opening.

Pivotally mounted for rotation on a screw or stud 17 secured to the adjacent wall of the weight receiving pocket 7 and at the upper end of the closure receiving opening is a locking member 18 having its peripheral edge extended to form a locking hook 19 adapted to engage a screw or lug 20 secured to the inner face of the pocket piece 11 whereby when the hook is in engagement with the locking stud 20 the pocket piece is effectually locked against accidental displacement.

The peripheral edge of the locking disk or member 18 is provided with one or more apertures 21 adapted to register with a recess or opening 22 formed in one end of the pocket piece 11 and through which a nail or similar tool may be introduced when the parting strip 14 is removed so as to cause the locking member to be rotated on the pin 17 out of engagement with the locking stud 20 and thus permit the pocket-piece 11 to be removed.

When it is designed to obtain access to the interior of the weight-receiving pocket 7 the parting strip 14 is removed and a nail, screw-driver or similar-tool introduced through the opening 22 into the adjacent aperture in the locking plate and said plate rotated on its axis to released position, after which a slight inward pressure is exerted on the lower end of the pocket piece which forces the opposite end thereof laterally beyond the adjacent face of the stile 6 so that the same may be conveniently grasped by the hand and removed from the closure receiving opening without danger of scratching or otherwise Inarring the wood Work.

In order to replace the pocket piece one end thereof is inserted within the closure receiving opening and positioned against the spring 16 after which the opposite end of the pocket piece is forced inwardly and the locking plate rotated to operative position by inserting a tool through the recess 13 in the manner before described. It will thus be seen that one of the inclined ends of the pocket piece is yieldably supported in engagement with the correspondingly inclined end wall of the closure receiving opening while the opposite holding and locking the pocket piece against accidental displacement.

If desired the position of the locking member and spring clamping plate 16 may be reversed, that is to say the spring plate may be positioned at the upper end of the window' frame and the locking member at the lower end thereof.

Having thus described the invention What is claimed is:

1. The combination with a window frame having a weight receiving pocket and provided with an opening communicating with said pocket, a pocket piece forming a closure for said opening, and a locking member mounted for rotation on the frame within the weightreceiving pocket and adapted to engage the pocket piece, there being a recess formed in one end of the pocket piece for the reception of an operating tool.

2. The combination with a window frame having a weight receiving pocket and provided with an opening communicating with said pocket, a removable pocket piece forming a closure for said opening and having its inner face provided with a stud, and a locking member mounted for rotation on the frame within the weight receiving pocket an dprovided with a terminal hook adapted to engage the stud, there being a recess formed in the pocket piece for the reception of an operating tool.

3. The combination with a window frame having a weight receiving pocket and provided with an opening communicating with said pocket, a pocket piece forming a closure for the opening and having a recess formed therein, a locking member mounted for rotation in the weight receiving pocket and adapted to engage one end of the pocket piece, there being an aperture formed in the locking member and adapted to register with the recess in the pocket piece for the reception of an operating tool.

4. The combination with a window frame having a weight receiving pocket and provided with an opening communicating with said pocket, a removable pocket piece forming a 'closure for said opening and having a recess formed in one end thereof, a stud secured to the inner face of the pocket piece, a locking member mounted for rotation within the weight receiving pocket and pro vided with a terminal hook adapted to engage the stud, a spring plate secured to the interior walls of the weightreceiving pocket and bearing against the adjacent end of the pocket piece, there being an aperture formed in the locking member and adapted to register with the recess in the pocket piece for the reception of an operating tool.

In testimony that I claim the foregoing as my own, I have hereto afiixed my signature in the presence of two witnesses.

CHARLES l3. SMITH.
